86 It is safe to reuse now.
88 @anchor{Release 5.0.0}
90 Backward incompatible remove of excess misleading @code{gost3410.Mode}
91 from all related functions. Point/key sizes are determined by
92 looking at curve's parameters size.

96 @strong{Fixed} nasty bug with Edwards curves using in 34.10-VKO
97 functions: curve's cofactor has not been used.
